Space for motors from Pyro 700 to Scorpion 5020
Adjustable ger "width"
Original D3 "look like"
Batteries in the middle of the frames (changeing them without taking of the canopy)

Enough space for batterysize like 12s 5000mAh

At the moment I have the wooden prototype, because I wanted to check all the holes I drawed!
Next week I will mill the motor mount and a helical main gear (one with 96 and one with 100 teeth) for a more silent heli!Raw weight without blades, but with canopy and:
Flybar Head
Plastic tail
G10 fin
Aluminium tail boom
Aluminium tail supports

are 2130g (without canopy 1950)

If I add my batteries (12s 3800mAh - 1200g), 3x swashplate servos, gyro (heavy GY611), tailservo, receiver batteriy (2s 1800mAh), receiver, scoprion 5020, jive 120, and some blades I will get a flightweight around 4700 gramm (without any other tuning, a heavy motor, and big receiver batterie)!!
I think that's not so bad, it's less than the nitro version and more powerfull together!
